The time when the cement slurry's column pressure reduces to the water column pressure before or after initial set is directly related to whether or not formation fluids flow out during wait-on-time.
水泥浆的有效浆柱压力是在初凝前还是在初凝后降低至水柱压力，直接关系到能不能在固井候凝过程中压稳地层流体、实现压稳防窜候凝。
It can be seen that the initial maximum pore water pressure takes place in the lower soil due to the load transformation from pile cap to soil.
